Product Description

The TN009 is a 5-in-1 multifunction composite instrument for placing, packing, shaping, and carving.

In 2007, Garrison Dental Solutions introduced TN009, a 5-in-1 multifunction composite instrument. The TN009 includes 2 sizes of condensers, 2 interproximal carvers, and an acorn carver. The 9 dentists who participated in this evaluation initially used the instrument for 4 weeks.

Several evaluators said they found the instrument cumbersome and compared it to their single-tipped instruments. The editorial staff at Dental Product Shopper decided to give the evaluators another 4 weeks to use the instrument to see if more time would eliminate some of the discomfort.
When the evaluators gave their feedback after the second 4 weeks, some found that the instrument became easier to use, but others found they still weren't satisfied. For those dentists who are interested in finding ways to save time in their daily tasks, the time needed to get used to the instrument was worth it. Some of the other dentists weren't willing to give up the comfort they feel with their current instruments.

Working Characteristics

When the evaluators were asked about the importance of working characteristics (ie, does composite stick to the instrument or pull away from the tooth) when purchasing a composite instrument, all 9 said they are very important. The evaluators were then asked to rate the TN009 composite instrument on its working characteristics. Five rated it as excellent and 4 rated it as very good. One evaluator said the instrument 'didn't stick to composite at all.'

Carving Composites

According to Garrison Dental, the TN009 has 2 ultrathin interproximal carving blades for trimming flash and placing final anatomical touches on composite restorations. The 2 condensers are sized for both conservative and wide preparations, and the acorn carver has been sized and shaped to help create occlusal anatomy.
When the evaluators were asked to rate the TN009 on its ability to carve modern composites, 8 rated it as excellent to good and 1 rated it as poor. One evaluator said, 'The different tips are a good shape, but the angles are difficult and I keep gouging the composite with one tip as I turn the instrument to use a different tip.' Another evaluator said, 'I really liked the variety of shapes to allow me to condense rather than actually carve composite away. Once condensed well, the blade parts very easily removed the excess material.'

Using All 5 Instruments

When the evaluators were asked to rate the TN009 on their ability to use all 5 parts of the instrument on a typical patient, 5 rated it as very good to good, 3 rated it as fair, and 1 rated it as poor. At the end of the first 4 weeks, one evaluator said she found the instrument 'a bit too busy. I'm used to switching instruments and with all 5 heads it gets confusing.' When she was asked the same question at the end of the second 4 weeks, she said, 'I definitely got used to it the more I used it. Still a bit busy, but overall a good instrument.' Another evaluator said there is 'too much stuff.' A third evaluator said that he 'rarely use[s] all 5 [parts], but I do use different parts in different situations.'

Time Savings

The manufacturer says that incorporating 5 instruments into 1 helps to simplify tray set-up and reduces the number of instrument exchanges between the dentist and assistant, saving time and money.
The evaluators were asked to rate the TN009 on its ability to save them time at chairside. Eight evaluators rated the instrument as excellent to good and 1 rated it as poor. One evaluator said that she has a relaxed office with lots of time to spend with each patient. She said that for her the time savings is 'not worth the learning curve.' Another evaluator said, 'It was of particular interest to me how much easier it was to work without having to change instruments. Estimating that switching instruments takes 15 to 20 seconds, actual time savings was probably only a minute. More important was the fact that I was able to do a better job because I had different shaped instruments at my ready.'

Overall Satisfaction

When the evaluators were asked to rate their overall satisfaction with the TN009, 6 rated it as excellent to good, 2 rated it as fair, and 1 rated it as poor. One evaluator commented that he felt the instrument is cumbersome and that 'it is just as easy to switch instruments, assuming 4-handed dentistry is in place.' A second evaluator said 'it took a few patients before I quit looking at the complex head and started using it as designed. The fact that I didn't have to change positions or instruments allowed me better position and less extraneous chairside movement.'
